HINGE.

Application filed July 21, 1923. Seria'l No. 652,958.

T o all whom z't may concern.'

Be it known that I, CHARLES S. BU'rrER- FIELD, a citizen of the United St-ates, and a resident 'of San Francisco, county of San Francisco, and State of California, have invented a new and useful Hinge, of which the following is a specification.

The resent invention relates to im rovements 1n hinges and its particular object is to provide a hingefor a doorY or the'like that will allow the door to 'be raised while the same is bein opened and to fall back to its original sition during thel closing act-ion. It is particularl proposed to utilize for this purpose a spira groove in the hinge pin and a ball riding in the same 'engaging a recess in the moving hinge member. It is further proposed to provide a particular construction which allows of the easy assembling of the hinge and of theinsertion of the ball into the spiral groove without furnishing any possibility of the ball leaving` the groove during the operation of the device. Further objects and advantages of my device will appear as the specification proceeds.

The preferred form of' the invention is illustrated in. the accompanying drawings wherein Fig. 1 shows a front view of a door secured to its support by means of my hinges, Fig. 2 a vertical sect-ion drawn along line II-II of Figure 1, Figure 3 a detail view showing my hinge detached in a closed position, Figure 4 a detail view showin the hinge in an open position, Figure 5 a horizontal section taken along line V-V of Figure 4.

Figure 6 a detail plan view of a ball used in my device, Figure 7 a side view of the same, Figure 8 a side view of. my hinge pin, Figure 9 a bottom plan view of the same and Figure 10 a horizontal section along X-X of Fi j re 8. While I have shown onl the pre erred form of my invention I wis it to be understood that fvarious changes, and modications may be made within the scope of the claims hereto attached without departing from the spirit of j the invention.

The door (1) is secured to the support (2) by means of the two hinges (3). It will -be noted that the upper edge (4) of the door engages the door frame on a slanting plane while the bottom edge (6) of the door is provided with a lining (7) of rubber or any other yielding material allowing of a yielding engagement. of the bottom of the door Nvith the top ofthe floor (8) disposed underneath the door.

The principal parts of the present inventlon are the hinges (3) one of which is Shown in detail in the Various figures. It comprises the two hinge members (11) and (l2) and the hollow pin (13). The latter which is shown in detail in Figure 8 is provided With a spiral groove 14) in its outer face and the groove terminates at its upper end in a hole (16) in the wall of the pin. The pin is in length oo-extensive with the hinge member (12) and adapted to be engaged by the two projections (17) of the latter which encircles the upper and lower parts of the pin and leaves a considerable space between the same free for engagement with the project-ion (18) extending from the hinge member (11). The latter part-Y occupies only a portion of the space left between the two projections (17) and is allowed to slide vertically on the sleeve.

'.l`his sliding motion, however is converted into a spiral motion by the ball (19) riding in the groove (14) and enga-ging with a recess (21) in the projection (18) of the hinge member (11). 'It will thus be seen that when the hinge member (11) is turned relative to the hinge member (12) it will slide upwardly on the pin (13) while on the re.- Verse motion it will slide downwardly.

In assembling the hingethe ball is inserted into the groove 14) through the hole (16). It is necessary that when the ball is inserted the recess (21) in the projecting member (18) registers with the hole (16) to.allow the ball to enter the groove. It will be seen, from Figure 4in particular that this situation can be brought about only before the pin is in its final position since in the4 position shown in Figure 4 the hole (16) is too high to allow the recess (21) to register with the same. It is necessary therefore, to slide the pin downwardly relative to the hinge member (12) for the purpose of allowing the recess (21) to register with the hole (16) whereupon the ball may be inserted through the hole from the in- Side of the hollow pin. The pin then may be turned slight-ly and pushed into its 4linal position which will cause ythe ball to ride in the groove (14) into the position shown in Figure 4. It will be readily seen that as -long as the pin occupies the position shown 1in Figure 4 the ball will never pass over the hole (16) again and thereA is no danger therefore, that the ball may drop out of its engagement. v

To hold the hollow pin in its operative position I provide the bolt (22) shown 1n detail in Figures 6 and 7. The same is provided with ahead (23) and an embossment (24) fitting into the hollow pin. Its .head is provided with a transverse-member (26) fitting mto -registering recesses (27) of. the

' pin and (28) of the projection (17) of the hinge member (12) so that when the bolt (22)is pushed into place and is properly engaged .'t holds the pin (13) against rotary motion. A nut (29) preferably of the same form as lthe head (23) engages the threaded end ,(30) of the bolt (22) on the opposite end and holds the bolt in place.

The fact that the hollow pin (13) is held against rotation furnishes further insurance- `against the dropping out of the ball. Norrecess (21) except when the pm (13) is turned and lowered at the same time.

To assemble the hinge the best way to proceedvis as follows: The hollowpin 1`s passed through the holes in the projections of the two lhinge members in suc manner that the distance ofy the hole (16) from vthe upper projection at least equals the distance of the recess (21) from the same line. The pin is then held so that the hole (16) ointsdownwardly and the ball inserted, w ereupon the pin YVis' shaken until the ball rolls into the hole. The recess (21) is then brou ht into -registry 4with the hole so that the all engages with the recess, whereupon the hinge "member (11) is turned so as to force the hall into the wspiral groove (14). The pin.

is then pushed upwardly into its final position and turned to allow the transverse member (26) of the ball (22) to be engaged with the respective notches in the hollow pin and the projection (17 of the hinge member (12) whereupon the nut,(27) may be engaged with the bolt for-fholding the same in place. The hinge is nowready to.

be attached to the door and the door frame. J It will be noted that the particular construction of the hinge allowing of the raising and the lowering of the door makes it unnecessary to provide a threshold underneath the same which is a very important feature of the present invention. The rubber slip at the bottom of the door serves to make the door dust and draft proof. The hinges of course may be constructed to allow the door to ope-*1 either to the right or to the left.

I claim: -1. In a hinge, a hollow pin' having a spiral groove in its outer face, a hinge member supporting the pin, a second hinge member plvoted to the pin and a ball slidable in the groove engaglng a recess in the second hinge member for imparting spiral motion to the latter, the spiral groove terminating in a hole in the wall of the pin above the normal travel of the ball which allows of theinsertion ofthe ball while the hinge is assembled.

2. In` a hinge, a hollow pin' having a spiral groove in its outer face, a hinge member supporting the pin, a second hinge mem# ber pivoted to the pin and a ball slidable in the groove engaging a recess in the second hin e member for imparting spiral motion to t e latter, the spiral groove terminating in a hole in the wall of the the insertion of the ball While the hinge is assembled and means being provided for locking the pinin a detiniteposition placing the hole out of lthe normal range of the ball during the operation of the hinge.
